Linear molecular formula: C6H5CH=CHCOOCH2C6H5. The structural formula is as follows:[ Common Chemical Reactions ] Benzyl cinnamate is an organic carboxylic acid ester, therefore it has some common properties of organic esters and can undergo hydrolysis, acidolysis, alcoholysis, and other reactions.[ Forbidden compound ] Strong oxidant, strong acid.Polymerization hazard: No polymerization hazard.Main purpose(1) As an ester synthetic flavor, benzyl cinnamate is mainly used as a fixative for oriental essence and artificial cologne, and also as a soap flavor.(2) Used as a UV absorber. Mainly used for sunscreen and tanning cosmetics. The maximum absorption wavelength of ultraviolet light is 310nm. The addition amount is usually less than 5%.(3) It is used in the formula of edible essence, and is often used to prepare apricot, cherry, pineapple and other fruit flavor essence.manufacturing method The synthesis method of benzyl cinnamate is as follows:(1) The main methods used are esterification and condensation: esterification is achieved by neutralizing cinnamic acid with sodium hydroxide and then esterification with chlorotoluene. The condensation method is obtained by condensation reaction using benzyl acetate and benzaldehyde as raw materials.(2) Using natural substance extraction method: The natural substance extraction method is the extraction of benzyl cinnamate present in Peruvian balsam, Turu balsam, and benzoin.(3) Direct esterification of cinnamic acid and benzyl alcohol: transesterification of benzyl alcohol and methyl cinnamate; interaction of sodium cinnamate and benzyl chloride; Claisen condensation of benzyl acetate and benzoic acid.Industry Chain[ Reference quality index ] Purity ≥ 99%Toxicity and Environmental ImpactBenzyl cinnamate is non-toxic and irritating to the skin and eyes in contact with rabbit skin, 500mg/24 hours, with mild reactions; Acute toxicity: Rat oral LD: 5530mg/kg; Guinea pig oral LD: 3760mg/kg.GB 2760-1996 stipulates that edible spices are allowed to be used. It is mainly used to prepare honey, pear, apricot and other essence.Packaging, transportation, and storagePackaged in plastic lined cardboard barrels or paper bags, stored in a cool, ventilated, rain proof, and sun proof warehouse. Keep away from sparks and heat sources. It should be stored separately from oxidants and avoid mixed storage and transportation.
